Title: Resilient connection between hollow members - is multiple arm resilient member receiving arrow shaped insert housed in C=shaped recesses
IPC: E06B3/263
Filed: 1977-04-04
Abstract: The connection between two hollow members (1, 2) is made by a locking strip (8) which is pushed between them until it is flush with the outside surfaces. The hollow members have partitions and the two longitudinal positions at the joint region have return flanges (19, 20) forming two C sections with the joint gap between them. These two sections house a sealing strip (4) between which the locking strip is engaged. This sealing strip has two sloping arms (15, 16) to engage the outside parts of the recess and two straight arms (9, 10) to engage the inner parts. A bridging part (5) between the sides (11, 12) carrying these arms has lugs (6, 7) forming a pocket for the tip of the inserted locking strip. Just above, two resilient arms (17, 18) are bent inwards by a bulge on the locking strip, as it is inserted forming a good seal.

Title: Torque sensor with spiral spring connecting rotating parts - has contactless spring deformation sensor obviating pressurised capsule
Inventor: MUELLER ALFRED DR ING
IPC: G01L3/14
Filed: 1978-11-28
Abstract: A torque sensor has a force transfer spiral spring between two parts (2, 4) rotating about a common axis (30). Spring displacement causes a distance measurement device to produce a corresp. output signal. It is of very simple construction and operates without requiring a pressurised chamber. Use of an inductive or capacitive distance sensor enables contactless measurement of spring displacement. The spring (8), which exerts a restoring force on the moving parts (2, 4), is mounted with one end on each so that relative motion of the parts varies the distance between the ends of the spring. The spring deformation in a direction perpendicular to the relative motion of the spring ends is a measure of the torque. Several springs may be arranged on a circle concentric to the rotation axis (30) with max. deformations occurring parallel to the axis.
Patent DE-2900622-A1 (DE)
Title: Voltage converter for use with solar cells - whose oscillation frequency is regulated by available solar radiation with period of current flow phase determined by timing circuit
Inventor: ROHDE NOTHART DIPL PHYS
IPC: H02M3/156
Filed: 1979-01-09
Abstract: The circuit is intended to match the load impedance on the solar cell, or other low voltage output energy converter, such as a thermocouple, to the available output energy. The converter works on the principle of a blocking oscillator under the control of a monostable flip flop (7). The frequency of the monostable is set by the state of a photo-sensitive resister (8) which receives the same irradiation as the solar cell (4). The monostable operates a switch, typically a field effect transistor (2), which alternately blocks and re-leases the flow of energy from an inductor (1) to a load, for example an accumulator (5). Increasing irradiation increases the time constant of the monostable which has the effect of decreasing the load impedance connected to the solar cell. During the current flow phase the input voltage generates a magnetic field, whose energy is passed to the load during the blocking phase.
